My trip leader is unable to travel due to COVID concerns but the rest of us are still interested in going. Unfortunately we haven't had any luck getting through to the rangers to see if there's any way to note this on the permit but in the past they've never allowed you to add alternate leaders once you're registered. Anyone have advice? Anyone who has hiked this year, have you run into rangers on the trail? We'll have his permit... he just won't be there.
